When driving, there are the following possibilities:
-
D = Automatic mode
When the selector lever is in position "D", gears are selected by the adaptive transmission control.
•
Gearshift using gearshift paddles
If the selector lever is in position "D" and a gearshift is initiated using the gearshift paddles, the automatic
transmission will automatically change to manual mode.
If no gearshift is made and the vehicle does not accelerate significantly within 6 seconds, the automatic
transmission will change back to automatic mode.
-
SD = Automatic mode, sport program
When the selector lever is moved to the right from position "D" into the shift gate "M/S", the automatic
transmission's sport-shift program is activated. The display in the instrument cluster changes from "D" to "SD".
•
M1 to M6 = Steptronic
If the selector lever is in shift gate "M/S" and is briefly moved to "-" or "+", the electronic circuitry changes to
Steptronic. Permanent manual mode is activated with the selector lever or gearshift paddles. The display in
the instrument cluster changes from "SD" to "M1" to"M6".
In manual mode (Steptronic), upshifts and downshifts are only executed by the transmission control if road
speed and engine speed are suitable. Gearshifts that would result in an excessively high or low engine
speed are suppressed.
-
Sport program via SPORT button
When the SPORT button is pressed, the electronics will change to the sport program regardless of the drive
range engaged or the current selector lever position.
